Abstract From the Canadian patent

A self-loading controlled deflection roll is rotatably mounted with non-self-aligning bearings at either end to bearing housings which, in turn are, pivotally-mounted to support stands. The stationary support beam extending through the roll is pivotally-mounted in the same support stands. At one end of the roll, a drive shaft having a drive gear engaging a ring gear which is mounted on the end of the roll shell concentric with its surface is provided to rotatably drive the roll shell while simultaneously permitting lateral movement of the roll shell relative to the support beam during the self-loading phase of roll operation.
